The phrase "21 S on a D" suggests that there are 21 sides on a die, which is not typical since standard dice have up to 20 sides. Assuming "19 AN of P" relates to the same context, it's unclear what "AN" or "P" refers to. The question seems to involve a riddle or code that needs further clarification to provide an accurate answer.
